This screen allows you to clear the history of error.     
You can see the error data points and their dates on screen.    If this screen displays Zero and/or Cal 
errors, you may check the error measurements as well.  You may scroll through the screen by 
upward-pointing and downward-pointing arrows if more than 10 error data points are listed on a 
display.    Up to 50 error data points can be displayed.

12TOOL CONTROL 
UEC can memorize the total fastening number and pulse number since a tool is brought into use.    It 
enables UEC to provide a notice of simple maintenance such as oil change by [WARNING 
COUNT/PULSE] and parts replacement/overhaul by [REPAIR COUNT/PULSE].   











TIGHTENING COUNT (Total tightening count number [1 unit: 10,000 fasteners]) 
Default: 0 
Setting range: 0 – 99999 [1 unit: 10,000 fasteners] 
CThis is total number of fasteners that the present tool now...

  
WARNING PULSE (Warning pulse number [1 nit: 10,000 pulses]) 
Default: 0 
Setting range: 0 – 9998 [1 unit: 10,000 pulses] 
CUEC displays a warning message when the total pulse number reaches preset pulses.   
CSet the number of pulses that you are going to repair like oil change a tool next time.     
]Display status when number of pulses reaches warning pulse^

13Functions 

Fastening control
Fastening control method is selectable from 5 options. 
  Control method  :  1  Torque monitor  
   :  2  Torque control  
    :  3  MC/EC wrenches Torque control   
    :  9  T type wrenches Torque monitor 
 
1)  Torque monitor Control method: 1 
This is used mainly for torque monitoring of the angle nutrunner UAN series, which shuts off by 
mechanical clutch.  When 0 is set to EXTERNAL START, UEC starts torque measuring by the 
external start signal...

 & 
3)    MC/EC wrenches Torque control Control method: 3 
This is to control torque of either MC or EC wrenches.  UEC starts torque measurement when 
detecting the start torque or greater torque, and switches on valve terminal to stop the tool when 
reaching torque cut level.    UEC provides judgment when judgment delay timer comes up after torque 
gets lower than start torque.     
When torque measurement delay timer is set up, it starts functioning when detecting start torque or 
greater torque....

  
5)  T type wrenches   Torque and fastening time monitor   Control method: 9
UEC monitors torque and fastening time of shut off tools.  






 
 
UEC starts torque measurement when detecting the start torque or greater torque, judges the tool is 
shut off when provides judgment when the fastening time between peak torque (x in a graph) gets 
longer than the judgment delay timer, and provides judgment.   
After UEC provides judgment, reverse completion delay timer gets functioning when the...

 
Upper and low limit judgment

UEC provides judgment whether or not the detected torque, angle or pulse number is within upper and 
low limit.   
Upper and low limit judgment is made against torque or pulse numbers until fastening is completed.     
Upper and low limit of torque is set in TORQUE LOW and TORQUE HIGH in the BASIC SETTING 
screen.  
Upper and low limit of angle is set in ANGLE LOW and ANGLE HIGH in the MODE SETTING screen.   
Upper and low limit of pulse number is set in PULSE...

  (ANGLE LOW NOK) 

Touch panel display message [ANGLE LOW] 

Buzzer sounds.   

UEC outputs TORQUE NOK.     

(7)    Judgment when pulse number is lower than pulse number low limit.   
CTouch panel display message [PULSE NO.LOW] 

Tool’s LED lamp lights in yellow. 

Buzzer sounds. 

UEC outputs TORQUE NOK.

Note)    Above is an example of linear torque change curve.



1)  Start torque error 
UEC detects the time from the time when external start terminal is switched on till the torque 
reaches start torque, and provides the judgment if the torque reaches start torque before the start 
torque error detect timer comes up.     
[Note]  
CUEC could not detect the error if the preliminary fastening condition varies much per...
